Meeting your company tax return filing deadline is crucial for maintaining compliance and avoiding penalties. In the UK, all limited companies are required to file a Company Tax Return (CT600) with HM Revenue & Customs (HMRC), even if they make a loss or have no Corporation Tax to pay.
The company tax return filing deadline is 12 months after the end of your accounting period. However, it’s important to note that the payment of any Corporation Tax owed is due 9 months and 1 day after the end of the accounting period. This means you must pay any tax owed before the filing deadline.
